GeForce GTS 250 1GB vs Radeon HD 6670 (OEM) 1GB
Intro
The GeForce GTS 250 1GB has a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
